@helix-loop Thanks! The PR needs git commit --amend -s to get DCO to pass.

In the meantime, do we need both ppc64 and ppc64le? And what hardware did you test this on?

[helix-loop]

@dblock It would be better to have both, but I can only test and tested this on ppc64le.

Is this ready? Unit tests?

@helix-loop are you still working on this? What is left to get this from draft to ready-to-merge?

[helix-loop]

Currently not. I guess the Unit tests are missing to get this ready. However #3930 seems to be further.
